Method for replacing car key battery: 1. Purchase the original battery for the car key, ensuring the voltage and model are the same; 2. Remove the mechanical key, usually by pressing a small button and then pulling it out; 3. Use a small flat-head screwdriver to pry open the car key. There is usually a small gap in the middle of the key, and gently twisting will open it; 4. Pry out the old battery, install the new one, and reassemble the car key. Reasons for car key failure: 1. Car key issues: During daily use, the car key may run out of power. Pay attention to the usage method while driving—keep the locking and unlocking distances short, as longer distances consume more power. Avoid pressing the remote key multiple times when locking the car; 2. Car issues: When the car battery is low, the car key may also become unresponsive. Monitor the car battery's charge level to avoid running out of power while driving, which could affect normal use; 3. Environmental issues: If the car is parked in an area with strong magnetic fields or where thieves may use signal jammers to steal important items, the car doors may not lock or unlock properly. In such cases, it is recommended to handle the situation carefully.
